2. Mounting The panel heater is fitted vertically, i.e. with the connection terminal or fan facing downwards. To permit the required convection, a minimum clearance to the adjacent components must be observed. A safety clearance of at least 300 mm must be left above the heater in the case of heaters with fans, and 100 mm for heaters without fans. (For both a thermal safety clearance to the sides of 60 mm and 100 mm at the bottom is required). If these clearances are observed, the ambient temperature does not rise above 65 ˚C. 2.1 Snap-type fastening onto a 35 mm support rail DIN EN 50 022 (Fig. 1.1). 2.2 Screw fastening onto the mounting plate (Fig. 1.2).

Rittal enclosure heater assembly instructions

It should be ensured that the heater and connection cables are mounted firmly and securely. Electric cables must not touch the body of the heater fan and must not be routed directly past the hot air outlet. The heater must not be mounted in the vicinity of flammable materials.

Notes EN

3. Mains connection

4. Safety notes

The heater must be connected to a power supply of the voltage stated on the rating plate via the quick-connect terminals. The unit must be connected to the mains via an isolating device which ensures at least 3 mm contact opening when switched off. Electrical connections must be made using solid wire (max. 2.5 mm2) or stranded wire with wire end ferrules. Due to the specific characteristics of the PTC heater element, the momentary switch-on current may be up to 6 A. A slow-blowing fuse (gL) is therefore imperative. IEC 6100-4-5 requires that the customer provides safety devices for impulse voltages of more than 1000 V. The double connection terminal permits the cascading of several heaters and thus simplifies wiring. A separate thermostat (SK 3110.000) or a digital thermostat (SK 3114.200) must be used to control the enclosure temperature. The humidity of the air in the enclosure can be controlled by incorporating a hygrostat (SK 3118.000).

● When carrying out the electrical installation, it is important to observe all valid national and regional regulations as well as the provisions of the responsible power supply company. ● Electrical installation must only be carried out by a qualified electrician who is responsible for compliance with the existing standards and regulations. ● Use only original spare parts! ● The heater must not be touched while switched on : Risk of burns from hot surfaces! The heater must be allowed to cool for approx. 15 minutes after switching off.

Caution! Overvoltage peaks of more than 2 kV may destroy the unit. 3.1 Proper usage Rittal enclosure heaters were developed and designed in accordance with the state of the art and the recognised rules governing technical safety. Nevertheless, if used improperly, they may pose a threat to life and limb or cause damage to property. The heater is only designed to heat components and to be installed inside housings and enclosures. The manufacturer will not be liable for any damages caused as a result of improper use, or for incorrect assembly, installation or use. All risk is borne solely by the user.
